Bug description:
I'm filing this about gdb per Steve's suggestion, although this could
be an issue somewhere else.
I recently discovered that the apport-test-crash
(https://code.launchpad.net/~daisy-pluckers/error-tracker-deployment
/test-crashes) crash files produced for armhf are crash files without
CoreDumps. This happened sometime between 20160531 and 20161025.
I've recreated this on the porter-arm64 box with the following minimal
test case (generate-sigsegv-crash.py is from apport-test-crashes):
schroot -c yakkety-armhf
python generate-sigsegv-crash.py cat
Running this on both armhf and arm64 we can see the following
different output.
armhf chroot on porter-armhf:
47 Program received signal SIGSEGV, Segmentation fault.
48 0xb6f599e4 in read () at ../sysdeps/unix/syscall-template.S:84
49 84 ../sysdeps/unix/syscall-template.S: No such file or directory.
50 (gdb) Saved corefile /tmp/tmp840s08i1/my.core
armhf chroot on porter-arm64:
47 Program received signal SIGSEGV, Segmentation fault.
48 0xf772f9e4 in read () at ../sysdeps/unix/syscall-template.S:84
49 84 ../sysdeps/unix/syscall-template.S: No such file or directory.
50 (gdb) Unable to fetch the floating point registers.: Invalid argument.
Notice how there is no core file save on porter-arm64.
